Abstract
A system for recording intracardiac signals and for providing stimulation pulses and/or ablation energy at intracardiac locations. The system includes intracardiac terminals adapted to collecting intracardiac electrophysiological potentials from respective intracardiac locations in an individual; an indifferent terminal adapted to collecting indifferent electro-physiological potentials from the individual; a differential amplifier stage adapted to receiving and amplifying the electrophysiological potentials collected from the intra-cardiac and indifferent terminals with respect to a signal reference to obtain respective intracardiac and indifferent signals; a processor device adapted to determining a common mode signal as an average of the intracardiac and indifferent signals and adapted to providing an output of intracardiac data based at least on the intracardiac signals, wherein the intracardiac signals are referenced with respect to the common mode signal. A method of processing intracardiac electrophysiological signals is also disclosed.
